Here is the part of the code that I think is in charge for showing me
the list of possibilities.
It does use completing-read, but maybe using apply it doesn't work?
(Just wild guessing).

--8<---------------cut here---------------start------------->8---
          (list (if (and context (car context))
                    (format "%s(default: %s) " prompt (car context))
                (setq senator-jump-completion-list
                      (senator-completion-list in-context))
     (apply #'completing-read
            (if (and context (car context))
                (append completing-read-args context)
     in-context no-default)))
--8<---------------cut here---------------end--------------->8---

Thanks a lot this looks alos cleaner...
